New process for electroplating non-metal material surface and its special conductive paint

Abstract

The simplified process for electroplating non-metal material surface includes the steps of chemically deoiling the surface of non-metal material, spraying conducting paint for metallizing the non-metal material, and final electroplating copper, nickel or chromium. The conducting paint consists of filming resin 20-40 wt% , flaky conducting metal powder 28-40 wt%, coupler 0.5-2 wt%, orientating arranging agent 1-1.25 wt%, mixed diluent 20-40 wt% and assistant 0.5-2 wt%. The process is simple, low in production cost, high in work efficiency and environment friendship, and may be used in matallizing various non-metal material with complicated shape.

Description

1. Technical field [0001] The invention relates to a new process of surface electroplating of non-metallic materials and a special conductive coating thereof. 2. Background technology [0002] With the continuous development and progress of science and technology, polymer products are widely used in various fields of life and production. Lightweight and easy-to-form polymer non-metallic materials are generally used in electronic products, automobile industry, daily hardware, and various toys to replace traditional metal shells, but the appearance and decoration effect of polymer materials is poor. effect, usually surface treatment is required. A common method is to electroplate other non-ferrous metals on its surface, such as electroplating copper, nickel, and chromium. However, non-metal itself does not conduct electricity and must be metallized before electroplating. The traditional non-metallic electroplating process is: non-metallic products → chemical degreasing → ch...

Problems solved by technology

This method has a lot of process steps, and waste water is produced during the production process, which brings waste water pollution while obtaining decorative effects; Japanese Patent No. 1-301882 introduces a method of coating waterproof paint on non-metallic materials. and conductive paint, the method of electroplating after drying

Existing problem in the above-mentioned technological method is, conductive paint is difficult to have good adhesion with various non-metallic materials such as ABS plastics, glass fiber reinforced plastics, thereby can not guarantee to go out good metal coating on various non-metallic plating, In addition, the corrosion resistance of the waterproof coating is not strong, and it is required to add an electrode when the plating area exceeds 3-5 square decimeters.
